This sound library is sampled from a toy that has two modes, which are obviously "Piano" and "Xylophone". You can access these modes via key switches.
I made this virtual instrument so that is played back exactly like the original toy, right down to the quirk that necessitates that you press the keys down with a bit of force, in order for the hammer to hit the bells. If you don't, then you'll just hear the keys flailing and no tone.
This is a great oddity to add amongst ...

I'm creating a bunch of SoundFonts for myself and other musicians. Many of them are free and can be used in commercial and non-commercial projects. Here is the "lite" version of my virtual Hammond organ. The "full" version can be downloaded from my website.
